            Bug ID: 89571
           Summary: XFX 7300 GS - Black screen with DVI when KMS(nouveau)
                    starts - VGA working
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Driver/nouveau

Created attachment 114287
  --> https://bugs.freedesktop.org/attachment.cgi?id=114287&action=edit
vbios XFX Nvidia 7300 GS 256MB

I already talked in IRC #nouveau before reporting this bug.

Card:
http://images10.newegg.com/NeweggImage/ProductImageCompressAll300/14-150-410-02.jpg

Problem: Card connected to an 24" 1920x1200 monitor via DVI. Everything is
working fine with windows and DVI at full resolution.
When booting any Linux live, i get a black screen directly when KMS starts.
BIOS post and VESA works fine with DVI.
To get a picture with nouveau, i had to connect the same monitor via VGA cable
to the nvidia card. I get then an 1024x768 resolution.

After boot with VGA i remove the VGA cable and connect DVI to get some logfiles
for debugging.
first:
for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n
"${con#*/card?-}: "; cat $p; done

reports in VGA-mode:
DVI-I-1: disconnected
TV-1: connected
TV-2: disconnected

reports in DVI-mode (no working screen):
DVI-I-1: disconnected
TV-1: disconnected
TV-2: disconnected

The xorg log:
https://pastebin.mozilla.org/8825681

the dmesg:
https://pastebin.mozilla.org/8825682

The vbios from /sys/kernel/debug/dri/0/ :
http://www.file-upload.net/download-10414782/vbios.rom.html
(also attached to this bug as attachment)

The IRC log with some additional information that are maybe usefull:
https://pastebin.mozilla.org/8825683


Would be nice to get able to use this computer with nouveau and DVI with normal
resolution.

Please provide dmesg from a boot with

nouveau.debug=trace drm.debug=0xe

Both with VGA plugged in, and with DVI plugged in. Also, please attach files to
the bug, not pastebins (which expire). Include the full dmesg, not a grep for
'nouveau'. There are other things that are interesting in there.

A small note - there has been other XFX cards with messed up DCB table.
See the current kernel [1] for examples

Following boot command makes it possible to use the full resolution over VGA
cable in X:
video=TV-1:1920x1200 at 60
